What does DVR mean?

DVR means Digital VCR

A DVR is a device that has the ability to store broadcasts on a hard disk. This is sometimes a separate device but often also a functionality of a satellite receiver or digital decoder. A DVR is also often called a PVR (Personal Video Recorder), depending on the manufacturer/supplier. The capabilities of the DVR/PVR depend on the software used, but globally it can be compared to a VCR. Most of them also have the possibility to look back with delay (this means that you can watch while still being recorded). The more extensive versions also have access to the EPG, or the automatic skipping of advertisements.

What is a gadget?

A gadget is a thing

A gadget (a thing, Gizmo) is an article that is innovative and often cleverly designed. Often a gadget is a consumer electronics product (but it doesn't have to be). The technology or design is innovative, so a trendsetter likes to buy it. Often a gadget is also purchased as a status symbol. A gadget is especially interesting at the beginning (and even then it is more frequent for the entertainment purchased, and not so much for its functionality), later there are too many people who have it too, and it is not interesting anymore to have (or to show off). A gadget is often purchased online, in a special gadget or gift shop.

What does Jailbreak mean?

Jailbreak is escaping from jail

However, that is the translation from English. Nowadays, jailbreaking means cracking your hardware so you can do more with it. Since the advent of the IPhone, jailbreaking has become popular. Normally, the hardware (IPhone) is equipped with an operating system with limited capabilities. In the case of the iPhone you can only install applications from the itunes Store, after jailbreaking you can also install applications that are not in the itunes store. Jailbreaking is a fairly harmless process: a number of operating system files are modified (and can be rolled back if desired). The biggest reason to jailbreak is because more is made possible. When the APP store offers enough software, it is not necessary for most people to jailbreak their phone. Https://www.youtube.com/watch?v=zEbCzkcrXJk
